Based on the 570S Coupe, the MSO X takes inspiration from the GT4 race auto version of the supercar.
Each of the 10 cars gets a livery inspired by the F1 GTR cars from the 1990s, complete with a pylon mounted rear wing, like the 570S GT4, for an extra 100kg of downforce, and a gooseneck carbon fibre roof snorkel (just like the F1 GTR Longtail). They were handed over to their owners during a special event near Las Vegas and offer a tantalising glimpse of what McLaren's MSO division can offer.
All ten-yes, just ten-examples of the MSO X have already been sold and delivered to customers. And in true hypercar style, there's extensive use of satin finish carbon fiber across the entire bodywork, which includes the roof, hood, side skirts and engine cover, as well as a unique rear bumper that even has "cut-outs" to further aid weight reduction.
"Customers come to us with their thoughts and ideas and MSO works with them to set boundaries within which they can then let their imaginations run wild", said Jolyon Nash, McLaren Automotive Executive Director, Global Sales and Marketing.
Inside, the MSO X cars are nearly as focused as the GT4 racers they emulate, with carbon-shell bucket seats that complement the exposed carbon-fibre chassis. Carbon fibre bucket seats feature, as do exposed sill panels and a carbon fibre bulkhead that allows stowage space for a racing helmet.
For an even more immersive race vehicle feel, the centre tunnel storage bin has been removed to shave a few more grams, there's a raised, carbon fibre centre console that is featured in the 570S GT4, as well as a McLaren Track Telemetry and camera suite.
There's a racing harness if you go on track but a three-point seatbelt for a trip to the shops.
Befitting the fact that the MSO X cars are created to be driven on the road to reach a track, McLaren's reputation for road auto usability is at least partially retained, with parking sensors, rear view cameras, vehicle lift and race air conditioning on all the vehicles.
